5.7 Hemi Etorque Problems [Described]

When it comes to hemi etorques, many potential problems can arise. This is because the design of these devices is based on the assumption that the torques will always act in a certain way and that no other forces will be acting on them.

Finding a solution to the 5.7 hemi etorque problems is critical for the future of passenger cars. If not addressed, this issue will significantly impact the marketability and fuel economy of passenger cars.

However, this is rarely the case in practice. In this blog, we will discuss the most common hemi etorque problems and solve them.

5.7 Hemi Etorque Problems

5.7 Hemi Etorque Problems

5.7 Hemi-etorque is a problem that can happen in the engine when it’s at operating temperature and cold enough to cause it to hesitate or rev up very slowly until you back off on the gas pedal or put it into gear.

This issue occurs in all engines but is especially common with the 5.7 Hemi V8 engine. In this case, it’s caused by high-temperature deposits called sludge (from coolant), which clogs intake valves, causing them to stick closed at low rpm and high throttle openings (which causes hesitation).

The problems are as follows:

  • Misfires
  • Multi-Displacement System (MDS)
  • Exhaust Manifold Bolts
  • Engine Tick

Steps to fix misfires

There are a few different ways to fix problems with 5.7 hemi etorque, and each one has its own set of benefits and drawbacks.

Start fresh:

This is the first step in fixing a problem with 5.7 hemi etorque. When you start from scratch, you’re increasing the chances that something will go wrong.

Fresh starts are important in business because they help ensure that new approaches aren’t made that would be harmful to the company.

It’s also a good way of checking in with yourself and making sure that you’re living according to plan. 

Take your time:

This is another crucial step in fixing problems with 5.7 hemi etorque. If you don’t take your time, you won’t get anything right.

The best way to do this is to use this time to focus on what you need to do to get your company done. When you have everything in place, it’s essential to move forward with glee. 

Burns time:

If you try to do too much, you may end up doing nothing while also causing inconvenience to yourself. The best way to schedule things such as your work/student work/home activities so that you can give all of it the attention it deserves.

Is Etorque Worth It?

Is Etorque Worth It

We already know that eTorque improves engine performance by supplying more torque, but let’s go a bit further to discover what that entails.

First and foremost, there are no disadvantages to using eTorque. There is no loss of performance or other features as a result of using an engine with eTorque, so you don’t have to worry about that.

The eTorque motor on a Ram truck’s engine, arguably, accomplishes the most significant thing: it provides greater torque while the vehicle is at low speed, notably when the engine is operating at less than 2,000 rpm. 

The amount of torque provided varies on the engine: the 3.6L V6 engine receives an additional 90 lb-ft of torque from the electric motor, while the 5.7L HEMI V8 engine receives an additional 130 lb-ft of torque.

Because the eTorque motor replaces a typical alternator on the engine of a Ram vehicle, it also performs the function of an alternator. Typically, an alternator transfers power from your truck’s engine to the vehicle’s electrical systems.

The eTorque motor supplies this power to the electrical systems, which eliminates the need for engine power, allowing excess energy to be utilized for mechanical activities.

Because of the increase in torque at low speeds and the electric motor functioning, the maximum towing capacity of a Ram 1500 with eTorque may be more than 1,000 lbs more than a vehicle with the same engine but no eTorque.

The eTorque motor, like many hybrid and electric cars on the market, has a regenerative braking system. When you press the brakes in a standard vehicle, energy is wasted via heat into the surroundings around your automobile.

However, the eTorque motor may utilize that energy to power electrical systems rather than waste it with regenerative braking. This is determined by how you use the brakes.

How Does Etorque Work?

When you let off of the accelerator at a high speed, the eTorque’s motor/generator begins creating electrical energy, which feeds back into the battery system whilst still smoothing out gearbox downshifts.

It adds 90 lb-ft of torque to 130 lb-ft and V6 RAMs of torque to V8 RAMs. It contributes torque while shifting into and out of four-cylinder mode during V-8 cylinder deactivation, as well as during shifting.

The eTorque technology resets the vehicle and starts onward movement in 70 milliseconds after an auto-stop. A gasoline closed mechanism with interactive slowdown may also help you save money on petrol.

In 3.6-liter V-6 and 5.7-liter V-8 HEMI engines, eTorque replaces the RAM’s standard alternator with a more durable motor/generator. The Continental motor-generator for the eTorque-equipped V-6 is mounted in front of the engine, with the shaft facing the rear.

 A special, water-cooled coolant circuit is employed because the inner cooling fans in a conventional alternator would not operate in this layout.

A Magneti Marelli motor-generator is mounted typically towards the top of the HEMI V-8 engine, where air cooling is adequate.

The 48-volt eTorque system adds 90 pounds to the HEMI V-8 and 120 pounds to the V-6, accounting for the difference by the water-cooling circuit.

Generators only need a minimal amount of energy from the auxiliary drive of an engine. eTorque’s motor-generators, on the other hand, use their auxiliary crank shaft to slow and hasten those vehicles; as a result, the buckle must be longer, stronger, and loop all around shaft more tightly.

A fastener on each ends is also necessary to keep the belts taut when the engine switches from producing to driving mode. The eTorque Hem also gets a larger crankshaft pully, which improves the motor/leverage ratio.

The eTorque system’s electric energy is stored in a 30 pound, 430 watt-hour LG Chem battery pack installed on the truck cab’s back wall.

A DC-to-DC converter is included in the system to power the vehicle’s normal electrical demands and charge the 12-volt starting battery.

2022 Ram Etorque Problems

2022 Ram Etorque Problems

In 2022, there might be some problems with the ram etorque. This is because the etorque will no longer be able to keep up with the current level of energy demand.

As a result, a lot of infrastructures will start to fail, including power grids and oil refineries.

This will cause a lot of chaos and economic disruption across the world. Here are the common etorque problems in 2022-

  • Vehicles stall at greater highway speeds, whereas others experience engine stops at modest speeds while turning left or right.
  • Engines that stall while in motion alongside other cars on the road may create a hazardous scenario, making drivers more vulnerable to accidents and injury.
  • While driving, the engines in their RAM 1500 automobiles stall and shut off without warning.
  • The car automatically activates the emergency brake after stopping.
  • The engine stopped without warning.

Ram Etorque Battery Replacement Cost

The cost of a battery replacement depends on the model and the manufacturer. However, generally speaking, it is quite expensive. This is because most companies charge for labor and parts involved in replacing the battery.

The labor charges are normally between $30 to $50 per hour, while some even require an appointment which maybe another $20 or more to pay.

The starter generator is $1330.00, and the battery pack is $1575.00. if not more, just for one battery replacement! Not only that, but you will also need to do these every two years as batteries usually last around 2-3 years.

5.7 Hemi Etorque Review

Instead of a traditional efficiency-minded full-hybrid setup, the Hemi eTorque uses the 5.7 L V8 to power a 48-volt alternator, which charges a tiny battery below the rear bench.

This strengthened alternator then serves as a beginner for the fuel-saving auto-start-stop technology.

The eTorque arrangement does not increase the 410 lb-ft peak torque of the Hemi 1500 but rather evens out the torque curve at lower RPMs when the V8 runs slower.

As a consequence, there is an unnoticeable shift from electric torque to gasoline horsepower at high speeds, as well as some fuel savings along the route.

The hybrid’s meek personality carries over into the driving experience, scarcely exposing itself like most drivers save for an easily noticed charge indicator in the bottom corner of the instrument panel.

2021 Ram 1500 Etorque Review

2021 Ram 1500 Etorque Review

As far as the performance is concerned, this truck can haul a ton of stuff. It has a diesel engine that provides ample power and torque to get it through whatever you want to go.

The good thing about this truck is that it comes with an adjustable suspension, making the ride very comfortable on rough roads. You will be able to drive for long distances without any fatigue.

Also, if you are looking for something that offers great fuel efficiency, then I would recommend this truck because it gets up to 21 miles per gallon in highway driving.

It gets only 14 miles per gallon in city driving, which isn’t much but still better than some other trucks in its class like Chevrolet Silverado or Ford F-150. 

There aren’t many issues with this vehicle as far as safety is concerned. The airbags and seat belts provided in all four seats give your passengers additional protection while traveling with you.

Another thing that I like about this truck is its reliability and durability since they have been tested under extreme conditions and come out unscathed every time they are put through such tests.

3.6 Pentastar Etorque Problems

3.6 Pentastar Etorque Problems

Failure of an Oil Pump

Oil pump failures are a severe problem since they might result in a loss of oil flow. The ECU should promptly detect a decrease in oil flow and do all possible to avoid additional harm. The 3.6L oil pump failures seem to be a reduction in oil pressure rather than a total breakdown.

Problems with the Cooling System

Other systems, such as the oil cooler and heater core might fail as well. FCA manufactures the V6 Pentastar using sand casting processes.

Obviously, some sand deposits should be cleaned first before the head of cylinder can be installed. However, it appears that sand deposits may be detected in the engine after it has been produced on occasion.

Over time, sand builds in the cooling system, generating filth and layers throughout the system. This ultimately leads to Pentastar problems such as faulty water pumps, radiators, heating cores, and coolant.

Problems with the Rocker Arm

Considering also that slider arms are located in the head of cylinder, this makes sense. But, it’s not like all Pentastar crankshafts problems are alike . FCA issued a service bulletin for this problem, which we’ve documented below.

The whole repair advisory may be seen here. There is a superseding section in the 2014 advisory.

However, some newer Pentastar 3.6 L engines display the same difficulties. As a consequence, the amended portion does not seem to be a good option.

Failure of the Cylinder Head

This is a nice problem to start with since it predominantly affects earlier 2011-2013 Pentastar engines. Early 3.6L V6s had cylinder head problems on the left bank.

Burning up of the valve seats on cylinder #2 is the underlying reason.

Fiat-Chrysler fixed the problem in mid-2013 by using reinforced valve instructions and seats. They also tried their hardest to make things right for the clients.

The Jeep Wrangler looks to be the most vulnerable to 3.6L Pentastar cylinder head issues. However, the problem impacted a wide range of models.

Can Ram Etorque Be Turned Off?

Can Ram Etorque Be Turned Off

Having had 5 vehicles with automated start/stop, the RAM with eTorque is the first that We keep on since it is so quick that it does not disturb me at all.

We believe the eTorque battery is to blame for this. We’re not sure how it would be without it. However, you cannot stop it permanently since it is “persistent.”

Frequently Asked Questions

How long will eTorque last?

The standard three-year/36,000-mile Basic Limited Warranty covers the 2019 and 2020 Ram 1500 bumper to bumper throughout North America, from the body to the electrical system.

Furthermore, as part of the Basic Limited Warranty, the Federal Emission Warranty covers the Ram eTorque system’s following components for eight years/80,000 miles, whichever comes first.

The Ram 1500 is covered by eTorque warranties ranging from 1 year/12,000 miles to 8 years/80,000 miles.

Is Ram eTorque any good?

Many current trucks have these qualities as well, but the Ram is my favorite half-ton in general. It features a better on-road drive than any of its rivals, a more pleasant cabin, finer materials, and cutting-edge technology.

Does eTorque help with towing?

The eTorque technology substitutes the typical dynamo with a 48-volt belt-driven generator fueled by a battery. This upgrade enhances the performance, lift capacity, towing ability, and economy of the 2019 Ram 1500. It also improves the truck’s handling.

Does eTorque improve performance?

An eTorque engine, in principle, features an electric motor that improves torque, hence enhancing the performance of the vehicle.

This electric motor substitutes the usual alternator found on a normal engine, resulting in a light hybrid model for the Ram truck.


Hemi etorque refers to a steering system’s torque exerted on an engine. It is a common problem that can occur in any type of engine and is usually caused by insufficient lubrication or wear in the steering components.

As a result, the etorque struggles to provide the necessary resistance to turn the engine and cause slippage and vibration. I hope you have all the answers you were looking for.
